Super! How long do I need to boil it for once it hits the boil?

Someone told me to let it boil for 15 minutes. FYI.

How to tell if boiled eggs are done. I spoon out the egg from the water (after about 10 to 15 min.)and count to ten. If the egg is completely dry then it is done. It usually is med. boiled.
Try this trick it really works.
